ESnet at Berkeley Lab is hiring for a Network Performance Postdoctoral Fellow to help improve global scale data transfer performance.
ESnet provides the high-bandwidth, reliable connections that link scientists at national laboratories, universities and other research institutions, enabling them to collaborate on some of the world's most important scientific challenges. Funded by the Department of Energy (DOE) Office of Science, and managed and operated by the ESnet team at Berkeley Lab, ESnet provides scientists with access to unique DOE research facilities and computing resources.
A key ongoing area of technical investigation relates to the effective use of ultra-high-speed networks to transfer huge quantities of data on a global scale from the site of acquisition such as the Vera C. Rubin Observatory in Chile to processing sites on distant continents. To address these challenges, ESnet has recently embarked on an NSF funded project with partners at Florida International University to explore the use of temporal network state information as a basis for dynamically tuning end hosts transfer protocols to achieve better transfer performance.
We are seeking a Postdoctoral Fellow for Q-Factor to participate in the research and development of real-time network telemetry systems, and TCP congestion control tuning. In this role you will perform software development, conduct empirical assessment of techniques and publish results in collaboration with ESnet staff and external participants in efforts to improve global scale data transfer performance that will enable future network services and scientific workflows.
What You Will Do:
Contribute to research and development on the NSF Q-Factor project.
Implement systems that analyze network telemetry in real-time and perform actions on selected events.
Conduct research on TCP congestion control tuning using precision network telemetry.
Perform extensive network measurements on the ESnet testbed.
Document work and results in the form of journal papers and conference proceeding papers, and present work and results at scientific meetings.
Collaborate with other computer scientists, system engineers and our project partners at Florida International University.
What is Required:
PhD degree in Computer Science or related fields or an equivalent combination of education and experience.
Demonstrated expertise and understanding of common network protocols (e.g., TCP, UDP).
Demonstrated experience in performance analysis of computer networks.
Demonstrated creativity and the ability to perform independent research on computer networks and systems.
Knowledge of low-level system programming languages (such as C, Go or Rust).
Demonstrated ability to work effectively as part of a cross-disciplinary team.
Knowledge of declarative and functional languages.
Use of data plane programming and associated architectures and languages (e.g., P4).
This is a full-time 1 year, 9 month, postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds and ongoing operational needs. You must have less than 4 years of paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.
This position is represented by a union for collective bargaining purposes.
Salary will be predetermined based on postdoctoral step rates.
This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
This position has the option of working remotely.

About Lawrence Berkeley National Laboratory
In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular... views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
